__yield intrinsic

This intrinsic inserts a YIELD instruction into the instruction stream generated by the compiler.

In some architectures, for example the v6T2 architecture, the YIELD instruction executes as a NOP instruction.

Syntax

void __yield(void)

Errors

The compiler does not recognize the __yield intrinsic when compiling for a target that does not support the YIELD instruction. The compiler generates either a warning or an error in this case, depending on the source language:

  • In C code: Warning: #223-D: function "__yield" declared implicitly.
  • In C++ code: Error: #20: identifier "__yield" is undefined.
